Jabsco Profile M Flexible Impeller, Drive Type 7, 8-Blade, 2-9/16 in x 2 in, 5/8 in Shaft, Brass Insert

Overview

The Jabsco Profile M is a flexible pump impeller for marine pumps that use an 8-blade, drive type 7 impeller with a 2-9/16 in diameter, 2 in depth, 5/8 in shaft, and brass insert. It is used as a service replacement in raw-water cooling, bilge, transfer, and general-purpose flexible impeller pump applications where the pump model and impeller dimensions match.

This range keeps the same core fit across the listed configurations, with the material changing by variant. That makes material selection important: neoprene, nitrile, and natural rubber each suit different liquid conditions, especially when oil, diesel contamination, or cold-water service may be part of the job.

Key features

• Profile M flexible impeller format for compatible Jabsco pump applications.
• 8-blade construction for flexible impeller pumps used in water movement and onboard service systems.
• 2-9/16 in diameter and 2 in depth, matching the listed pump cavity size requirements.
• 5/8 in shaft size with a brass insert for pumps using this shaft and drive arrangement.
• Drive type 7 configuration, commonly listed for this spline-drive impeller style.
• Material options cover common marine pump duties, including standard water service, oily bilge or transfer conditions, and cold-water applications.

Variants

This impeller is offered in three material configurations with the same listed profile, blade count, diameter, depth, shaft size, drive type, and brass insert.

The main difference is the impeller compound. Match the material to the liquid being pumped and the service location on board rather than selecting by size alone.

• 920-0001-P: Neoprene. This is the standard option for many engine cooling and general water pumping duties, including fresh water or saltwater service where fuel or oil contamination is not the main concern.
• 920-0003-P: Nitrile. This material is used where bilge water or transfer liquids may be heavily contaminated with oil or diesel.
• 920-0008-P: Natural Rubber. This option is used for cold-water applications and should not be used with oily liquids or diesel.

Compatibility and fit

Before installation, compare the old impeller to the required profile, blade count, diameter, depth, shaft size, drive type, and insert style. Flexible impellers can look similar at a glance, so the 2-9/16 in by 2 in body size and 5/8 in shaft measurement are important checks before the pump is opened up.

This impeller style is commonly stocked as a spare for boats that rely on flexible impeller pumps for engine cooling or onboard water transfer. Keeping the correct material version aboard can reduce downtime during cruising, fishing trips, or seasonal maintenance.

Installation and care

Inspect the pump cover, cam, wear plate, and gasket surface while replacing the impeller. Blade tips that are cracked, missing, or permanently set can point to dry running, blocked intake flow, air leaks, or a worn pump body.

Lubricate the impeller with a pump-safe lubricant during installation, then confirm water flow immediately after startup. Flexible impellers are service items, so regular inspection is part of keeping raw-water cooling and utility pump systems dependable in saltwater use.
